Answer:
Use both methods to calculate the sale price of an item that costs $140 and has a discount of. 40%. 140 x.40 = 56. 140-56 +84. 140x.60 = $84.
Step-by-step explanation:
C
Answer:
x = 8 or x = -2
Step-by-step explanation:
x^2 - 6x + 9 = 25
x^2 - 6x - 16 = 0
The formula to solve a quadratic equation of the form ax^2 + bx + c = 0 is equal to x = [-b +/-√(b^2 - 4ac)]/2a
with a = 1
b = -6
c = -16
substitute in the formula
x = [-(-6) +/- √(-6^2 - 4(1)(-16))]/2(1)
x = [6 +/- √(36 + 64)]/2
x = [6 +/- √10]/2
x = [6 +/- 10]/2
x1 = [6 + 10]/2 = 16/2 = 8
x2 = [6 - 10]/2 = -4/2 = -2
Solution:
we are given wit a number 440.
we have been asked to write Write the value of the hundreds and the value of the tens in the number 440.
Here we can write
So value of the 100th place is 400.
Value of 10th place is 40
Here 
Hence the value of the number at 100th place is 10 times more than the value of number at 10th place.
One box of candy costs $1.50. A movie rental costs $2.
D seems to have the possibility of having the largest range.
